SALEM, Mass. (AP) — For a second straight year, boaters north of Boston are seeing unusually high numbers of long fin squid in local waters.

The Salem News reports (http://bit.ly/1ahjDeY) that the heavy concentrations of the squid are normally more common south of Cape Cod. Michael Armstrong of the Massachusetts Division of Marine Fisheries said this year's numbers are at least 10 times higher than normal.

The squid eat lots of smaller fish, such as herring, but they're also prey for larger fish, such as tuna and striped bass. Armstrong said it's too early to say if the increased squid are affecting native species.

The boom of the easy-to-catch long fin squid has attracted hordes of fishermen. Earlier this summer, Marblehead banned fishing from town-owned docks and floats because of overcrowding by squid fishermen.
